What problem or use case are you trying to solve?

After closing a CLI session, I would like to review the previous conversations I had, but there's no way to do this in the CLI.

AC:

• When a conversation ends, we should show the conversation ID so it can be resumed

• Support a new command like/conv that will show the most recent 10 conversations from ~/.openhands/sessions OR wherever the sessions are stored based on configurations.

It will basically list smth like:

- [CONVO ID 1] [Created at: XXX] Initial user message: ABCD...[truncated at 100 characters]
- [CONVO ID 2] [Created at: XXX] Initial user message: ABCD...[truncated at 100 characters]

• If the user has authenticated via their OpenHands Cloud account, we should also show the active conversations in the Cloud (active = a runtime is starting up or running) within the /conv list.

Implementation notes:

• You can find initial user messages by checking the JSONs ({0,1,2,3,4,5,6,...}.json in order) and look for "action": "message" and "source": "user" and get the .args.content field as the user message.

• We should allow the user to enter each conversation to view the [all user messages] from that conversation.

• We should also add a button and the button to move to next page/previous page.
